Stuck-Pipe NPT Cost Estimator

Enter your own rig day rate and an estimated non-productive-time (NPT) window to see what a stuck-pipe delay could cost on this well — a starting point for comparing recovery methods.

This is a simple day-rate × time calculation using the numbers you enter — it does not include mud, personnel, fishing tool rental, or other stacked costs, and it is not a Welong-specific savings claim. For context: industry estimates place total stuck-pipe costs at several hundred million US dollars per year across global drilling operations (SPE-160845-MS, Saudi Aramco), and a historical analysis of oil-spotting release attempts found only a 44% success rate with an average release time exceeding six hours — context for why a fast, decisive jarring release is worth comparing against slower recovery methods.
